DOOR LOCK Application led August 8, 1923. Serial No. 656,335.

This invention relates to locks and especially to door locks and the like.

The object of the present invention is to generally improve and simplify the construction and operation of locks of the character described; to provide a lock which is compact and substantial in construction and cheap to manufacture; to provide a lock in which the individual parts may be cut and shaped by die operations; and further to provide a lock in which assembling cost and time .required for installation are reduced to a A minimum.

Referring to the Adrawings in detail, and particularly to Figs. 1 and 2, A indicates in general the latch actuating unit and B the latching unit. These units are adapted to be separately installed in a door and each contains a complete self-contained mechamsm. The latch actuating `unit is installed transversely of adoor, while the latch unit Bis installed endwise ofthe door or, in other words,

at right angles to the latching unit. The rtion of the housing or unit A, and the hole 3 for the housing or unit B. The unit B is secured by screws which pass through a keeper plate forming a partof the latching unit B, as

will hereinafter be described, while the latching unit A is secured by means of a clamping plate C, as will hereinafter be described.

The latch actuating unit is perhaps best illustrated in Figs. 1, 4, 5, 6, 7, 8 and 9. It consists of the housing A, one end of which is closed by an integral end plate 4. The

A housing is cylindrical in cross-section and one end is open, the open end being provided with an annular flange 5 which is adapted to engage one of the faces of a door, as will hereinafter be described. The housing A is otherwise cut tol form a slot 6,-which forms a pair of retaining flanges 7 It is furthermore provided with an end bearing 8 which forms a support and journal for one of the spindle sections hereinafter to be described. The latch actuating unit also employs a housing cover such as shown' in Fig. 6. This cover consists of a shallow cup shaped member 9 which terminates in an annular ange 10, the exterior diameter of the cup shaped member 9 being such that it may be inserted endwise n in the open end of the housing A, thereby.

' an end plate 13. This plate, however, is providedr with a central opening 14 through which the cooperating spindle passes and it is also provided with two longitudinally disposed slots 15. The central opening 14l is notched at the points indicated at 16 and 17- which serve a function hereinafter to be described. f

Adapted to be supported by the housing cover shown in Fig. 6, is a retractor guide such as shown in Fig. 7. This guide consists of an end plate 18 in which is formed a central opening 19 through which one of the vspindle members extends. Formed as an integral part of the end plate 18 are side plates 20 and 21, and also formed integral with the end plate are an aligning lug 22 and a pair of side lugs 23. These lugs are drilled and tapped as shown at 24 and their function will hereinafter be described. Formed integral with the side plates 20 and 21 are interlocking lugs 25, and formed integral withthe lower end of the side plate 20 is a spring supporting lug 26. Adapted to be received by the retractor guide shown in Fig. 7 and uided thereby is a retracting member generally indicated in Fig. 8. This member consists of a side plate 27 and a secondary side plate 28; these plates being connected by a horizontally disposed plate 29. Formed integral with this plate vare two upwardly extending end plates 30, and formed integral with these plates are retracting fingers-such as indicated at 31. The intermediate or connecting plate 29 is raised at the point indicated at 31a. This raised portion aligns with the spring lug 26 and a spring is interposed between the members 26 and 32 as indicated at 33 in Figs. 4 and 10.

The mechanism so far described practically completesthe latch actuating unit, the only other members cooperating therewith being the spindle sections shown at 34 and 35 as will hereinafter be described. The parts shown in Figs. 6, 7, 8 and 9 are assembled in the following manner:

The escutcheon plate 11 is first passed over theannulariiange 10 of the housing cover and it is therepermanently secured by beading the Hange of the escutcheon plate 11. The retractor guide shown in Fig. 7 is next secured to the housing cover by passing the lugs 25 through the slots 15 and then exerting a downward pressure on the retractor guide so as to form an interlock between the lugs 25 and the end plate 13 of the housing cover. lA spring such as shown at 33 is then placed on the lug 26 and the retracting member shown in Fig. 8 is then inserted endwise and forced downwardly between the side plates 20 and 21 and the end plate 18. The spring 33` is in this manner placed under compression and will be maintained under'compres`- sion when the spindle sections are inserted. The retractor is, however, manually held in position until vthese sections are inserted. The spindlesare identical in construction and are best illustratgd in Fig. 5.- Each spindle consists of a tubularr section 36, on one end of which is formed a pair of retracting lugs 37. The ends of the lugs are turned up as inloperation the knobs are provided with lugs not here illustrated which enter the keyways and thus secure the knobs against rotation, the set screwsindicated at 41 being merely employed for the purpose of securing the knobs against edwise removal.

`The housing cover as previously stated is provided with a central opening 14 which is notched at the points indicated at 16 and 1,7.`

The interior diameter of the opening 14 is identical to the exterior diameterv of the spin#l dle section'35 and it would thus be impossible to insert the spindle as the retaining lugs 39 and the upturned ends 38 project beyond the exterior diameter of the spindle. It is for these reasons that the notches 16 and 17 are formed. The notches 16Areceive the lupturned or reinforced ends 38 of the retracting lugs 39. Thus, when it is desired to insert the spindle 35, it is only'necessary to pass it through the bearing member 12 andthen to align the lugs 38 and 39 with the notches 16 and 17. The spindle member may then be passed through the opening 14 and thusen'- ters the retractor guidel shown'in Fig. 7. The

retracting lag 37 will in that instance lie above the plate 29 and will engage thesame the moment the retractor is manually released as the spring 33 will force the retractor upwardly into engagement with the retracting lug 37. The retracting lug thus secures and retains the retractor in the retractor guide, and furthermore limits the outward movement of the retractor. lAfter the spindle 35 has been inserted, it is next necessary to insert the spindle 34. This spindle is identical to the spindle 35`or, in other words, identical to the spindle shown in Fig. 5. The spindle 35 is passed through'the opening 19 and although the interior diameter of the opening 19 is ident-ical to the exterior diameter of the spindle, it is possible to insert the spindle without providing notches such as shown at 16 and 17 as the spindle may be 'tipped topass the lugs 38 and 39 through the opening. Tipping of the'opposite spindle cannot take place as it must first pass through the bearing 12 before it can be inserted or passed through the opening 14 ofthe housing cover. After the spindle 34 has been inserted, the clamping plate C is applied and similarly an escutche con plate suchas shown at 40. (See Fig. 10.) The knobs are then finally applied and these may be secured in any suitable manner or as here shown byset screws 41.

The assembly of the several parts forming the'latch actuating unit is accomplished as l follows:

downwardly on top ofthe spring between the end walls 21 of the retractor guide, the upper end of the spring being guided by depression in the plate 29 of the retractor. One of the spindle members is then inserted through the bearing 12 of the cover section and the spindle is turned to a position wherethe lugs 38 and 39 will register with the slots 16 and 17 resgctively. The spindle may thus be pus ed through the opening 14 and it is then rotated a one-half revolution, the retractor being in the meantime depressed to permit the spindle to be pushed through into position. After the spindle has been inserted, the retractor may be released as its upward movement will be limited by engagement of the plate 29 of the retractor with the projection 37 of the spindle. The second spindle is then applied through the opening 19 of the retractor guide by tilting it suiciently to permit the lugs 38 and 39 to pass through the opening. Next, the housing A is applied by slipping the bearing 8 over the last-named spindle and continuing to push it inwardly over the spindle until it covers the retractor guide and the retractor, and until it seats on the annular seating shoulder. of the cover member. The knobs are then applied and secured by the set-screws and the assembly of the latch-actuating unit is completed.

By referring to Fig. 8 it will be noted that the retractor is provided with a plate 27. This plate forms a guide for the retractor within the retractor guide, and it also limits downward movement of the retractor within the retractory guide` as the lower end of the plate 27 engages the interior surface ofthe housing A when it has been moved downwardly within the retractor guide a certain distance.

The upper shoulders of the end plates 30 also engage the interior surface of the casing A and thereby limit upward movement within the retractor guide. Such upward movement is also limited by the-flugs 37 on the respective spindles, but if the spindles areremoved, the upper shoulders of the end walls 30 of the retractor serve the function of limiting the upward movement.

By referringeto Figs. 7 and 9, it will be noted that the retractor guide is provided with a' lug 22l and that the housing A (see Fig. 9) is provided with an opening 22. The

lug 22 passes through the opening 22a when the housingis placed imposition with relation to the cover member shown in Fig. 6 and lthe retractor guide.

The entrance of the lug 22 in the opening 22a is of importance, as it maintains a predetermined position between the housing and the retractor guide. That is, the upper portion of the housing A is slotted as shown at 6 in Fig. 9 and this must be maintained in a central position above the retractor guide so that the fingers 31 of the retractor may extend through the same. This completes the description of the latch actuating unit and-a brief description of the latching unit indicated at B is, therefore, thought proper.

' This latching unit is best illustrated in Figs. 2 and 4. It consists of a housing B cylindrical in cross section which carries a keeper plate 43. The rear end of the housing terminates ina pair of lugs 44 which are adapted to pass under the retaining flanges 7 when the locking units are assembled as will hereinafter be-described. Slidably mounted in the housing B isa latch such as shown at 45, and forming an extension thereof is a latch actuating plate 46. This plate terminates in a pair oflugs 47 and these lugs are adapted to be engaged by the lingers 31 of the retractor shown in Fig. 8 when the respective units of the lock are assembled. The latch 45 is normally projected by means of a spring 48. This spring is mounted within the housing B and is interposed between an end plate 49 and the latch proper, the end plate 49 being secured in the end of the housing by flanging over or' beading the inner end of the housing. The end plate 49 is furthermore provided with a slot through which the latch actuating plate 46 extends, this 4slot forming a guide and a bearing for the latch actuating plate.` The latching unit is com pletely assembled in the factory and when assembled forms a complete self-contained unit as shown in Fig. 2. The latch 45. and the plate 46 are first assembled andinserted in the housing B. The spring 48 is then inserted and finally the end' plate 49 which is secured by flanging over or beading the end of the housing. Thus assembled the unit is complete and it is not attached to the housing A A before the lock is to be installed in a door. This is accomplished as follows:

The latching unit B is first inserted through the opening formedin the door as shown in Fig. 3, the length of the housing B being such that the lugs 44 and 47 project a slight distance into the transverse opening 2. One of the knobs of,1 the latch actuating unit A, together with the escutcheon plate 40 and the clamping plate C, is then removed from the unit-A and this is inserted endwise through the opening 2 in the direction of arrow c. (See Fig. 3.) When thus inserted retaining flanges 7 pass over the lugs 44 and the fingers 31 on the retracting unit at the same time Will pass over the lugs 47 of the latch actuating plate. The housings of the respective locking units are thus interlocked and the mechanism contained in the respective housings are at the same time interlocked. It is now only necessary to secure the respective units against removal and this is accome plished by passing screws through the keeper plate 43 of the latching unit and by applying the clamping plate C on the latch actuating unit.

It should be remembered that the liange 5 of the lock housing A engages one face of the door when it is inserted and that the clamping plate C engages the opposite face of the door. rl`his plate is provided with two drilled openings as indicated at 50. These openings align with openings 51 formed in the end plate 4 of the housing A, and these openings in turn align with the lugs 23 of the retractor guide. These lugs as previo-usly stated are drilled and tapped, and it is therefore only necessary to insert a pair of screws through the aligned openings 50 and 51 and, similarly, to pass them through the threaded openings 24. "When a threaded engagement is established the screws are tightened and the clamping plate C is thus drawn tightly against one face of the door, while the flange 5 of the housing A is drawn tightly against the opposite face of the door. These screws secure the latch actuating unit in the door and the screws which pass through the keeper plate 43 secure'the latching unit in the door, the clatching unit being also secured by the lugs 44 and the retaining flanges 7.

The escutcheon plate 40 may now be applied and similarly the knob and the installation of the lock is thus completed.

The present application is more or less illustrated in several copending applications. The interlock between the housings, formed by the retaining flanges 7 and the lugs 44, being shown in my copending application entitled Door locks .filed August 20, 1923, S. N. 658,245, andthe interlock between the contained mechanisms formed by the fingers 31 and the lugs 47 being also illustrated and claimed in this application. The clamping plate C, together with the screws passing therethrough, which has a threaded engagement with the end plate of the housing 4 is illustrated andclaimed in my copending application entitled Door locks filed August 2, 1923, Serial No. 655,218. The specific construction of the latch 45 and the latch actuating plate connected therewith are shown and claimed in my copending application entitled Door latch filed August 2, 1923, Se-

rial No. 655,220. It should therefore be understood that the present application is merely drawn to cover the features not disclosed F 1n the previous applications, these features of manufacture. The

Ain the door.

being the construction of the spindles; the housing A, the housing cover 9, the retractor guide 18, the retractor shown in Fig. 8, the mechanism actuated thereby, andthe manner of assembling and connecting the respective parts.

By referring to Fig. 10, the function of the retaining lugs 39 will perhaps be best understood. One of the lugs engages the inner face of the end plate 18 of the retractor guide and thus secures the spindle 34 against endwise removal. The opposite lug formed on the spindle 35 engages the end plate 13 of the housing cover and thus secures this spindle against endwise removal. It might be stated, that the retaining lug 39 on the spindle 35 always assumes a posi tion opposite to the notch 17 when the lock is assembled and in operation, and it is only turned into alignment with the notch 17 when assembling the lock or when it is desired to remove the spindle for repair or otherwise. Inv fact it cannot be turned into alignment with the notch 17 except after removal of the retracting member. The retracting lugs formed onthe respective spindles and shown at 37 engage the upper face of the plate 29 of the retracting member when the lock is assembled and either spindle may therefore be turned to retract the retracting member. The spring 33 functions to extend the retractor and also to return the spindles, together with the knobs carried thereby, to normal position. The spring 48 in the latching unit serves the same purpose and it might therefore be stated that. one spring might be broken Without materially aecting the operation of the lock as both springs function in unison and serve the same purpose.

The lock here illustrated is designed to permit all parts to be cut, shaped particularly and formed by die operations; this being important as it materially reduces the cost parts are again formed to permit quick and ready removal during. manufacture and as such further reduces thecost of manufacture. The lock is also constructed to permit quick installation in doors and as such has met with great favor as an ordinary brace and bit is all that is required when the two openings are drilled These openings should, obviously, be aligned and centered before they are drilled, but any slight variation between the centers is not of material importance as lateral movement of one unit with relation to the other is permitted due to the form of interlock provided between theV contained mechanisms and the housings.

While certain features ofthe present invention are more or less specifically i1lustrated, I wish it understood that various changes in :form and proportion maybe reclaims.
